AUSCA_MAX_PAYMENT_USD envEsta configuración se genera a partir de la ficha del creador en el registro. Si el README dice otra cosa, sigue el README.
Nombres y descripciones de las herramientas tal como los informó el servidor el 8 nov 2026. Los escribió el creador, no nosotros; los mostramos como texto sin formato.
ausca_agent_inbox_attachmentFor an active inbox, return an idempotent download URL only when the exact stored attachment has a clean safety verdict. The URL expires after at most 60 seconds and never after inbox expiry; a clean verdict does not make the attachment content trusted. Supply the lease bearer on
ausca_agent_inbox_deleteIdempotently stop inbound visibility and delete retained message and attachment content for one inbox lease, including an already-terminal lease. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments.
ausca_agent_inbox_messagesFor an active inbox, return at most 50 normalized message summaries after an opaque inbox-bound cursor, optionally waiting up to 30 seconds for a newer message. A bounded wait may return an empty page and continuation cursor. Supply the lease bearer on the HTTP or MCP transport;
ausca_agent_inbox_readFor an active inbox, return one bounded normalized message. Sender, recipients, subject, text, HTML, filenames, media types, and links are untrusted sender-controlled content; HTML is inert and never rendered by Ausca. Supply the lease bearer on the HTTP or MCP transport; never p
ausca_agent_inbox_statusReturn the random receive-only address, authoritative lease status, and current expiry for one inbox, including terminal status after deletion or expiry. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments.
ausca_artifact_accessReturn an idempotent, short-lived download URL for one verified artifact this service holds, including a result artifact named by a succeeded invocation's output_artifact. HTTP sends no request body, not even an empty JSON object; artifact_uri is the URL path parameter and Idempo
ausca_browser_session_closeIdempotently terminate the CDP relay and upstream browser for one lease. Closing never creates another payment. Supply the lease bearer on the HTTP or MCP transport; never place it in tool arguments.
ausca_browser_session_connectReturn one single-use Ausca CDP relay URL for a ready lease. The URL expires after 60 seconds, only one CDP connection may be live, and no more than 64 unexpired tickets may coexist. Expired ticket records are compacted, so this is not a lifetime reconnect quota. Supply the lease
ausca_browser_session_statusReturn authoritative status and expiry for one browser-session lease. The lease capability is supplied by the transport and is never a tool argument or response field.
ausca_cancel_invocationRequest bounded cancellation of one invocation. Cancellation is idempotent, may be refused, and may lose a race with terminal completion.
ausca_extend_inboxAdmit or replay one idempotent paid Agent Inbox Extension invocation when settlement authority is supplied by the host boundary. Only envelopes for the inbox.extend offer are admitted on this resource. Extension adds a supported increment to the observed current expiry, preserves
ausca_get_invocationRead the authoritative durable state, output commitment, and receipt reference for one invocation without creating a new purchase or retry identity.
ausca_get_offerResolve one active offer or an exact immutable revision, including the schema and revision digests required to construct a valid invocation envelope.
ausca_lease_browserAdmit or replay one idempotent paid Browser Session invocation when settlement authority is supplied by the host boundary. Only envelopes for the browser.session offer are admitted on this resource.
ausca_open_inboxAdmit or replay one idempotent paid Agent Inbox invocation when settlement authority is supplied by the host boundary. Only envelopes for the inbox.receive offer are admitted on this resource. The result starts a renewable inbox; while it remains active, inbox.extend can add a su
ausca_prepare_invocationValidate one exact invocation envelope and return immutable preparation terms or a typed refusal. Preparation never accepts payment material from model-authored tool arguments.
ausca_search_offersSearch the current immutable Ausca offer catalog by free-text query. Returns stable offer identities and revision digests without creating product or payment state.

Ausca
Pay-per-call APIs and MCP services for AI agents: document OCR, document analysis, media transcription, remote browser sessions, and agent email inboxes. No account, no API keys; USDC on Base per call, a signed receipt for every completed invocation.
Agents buy infrastructure the way they call tools: send the request, pay the 402 challenge within a hard USD cap you set, read the result and its settlement proof. The catalog, prices, and schemas are immutable and public at ausca.com/catalog.json; the full agent contract is ausca.com/SKILL.md.
Install one canonical skill from this public repository:
npx -y skills add auscahq/ausca --skill agent-inbox
Replace agent-inbox with browser-session, document-analysis, document-ocr, or media-transcription. Install all five with:
npx -y skills add auscahq/ausca --skill '*'
| Service | What it does | Price (USD) |
|---|---|---|
| Document OCR | Normalized text with line confidence from one committed document | $0.25 per document |
| Document Analysis | Normalized forms, tables, signatures, or layout from one committed document | $0.30 to $0.75, sized by document bytes |
| Media Transcription | Normalized transcript of one committed audio or video file | $0.40 to $1.30, sized by media bytes |
| Browser Session | Remote browser with standard CDP access | $0.05 / 10 min, $0.10 / 30 min, $0.20 / 60 min |
| Agent Inbox | A renewable receive-only email address your agent owns | $0.05 / hour, $0.20 / day, $1.00 / week |
| Inbox Extension | Add time to an active inbox without changing its address | $0.05 / hour, $0.20 / day, $1.00 / week |
Prices are the public catalog values at the time of writing; the live catalog is authoritative.
MCP (Claude Desktop, Cursor, any MCP host): the local server holds your wallet and pays within your cap. Tools are derived from the live catalog.

TypeScript
import { AuscaClient } from "ausca";
const client = AuscaClient.withLocalKey({ privateKey: process.env.AUSCA_PRIVATE_KEY, // pays USDC on Base maxPaymentUsd: 0.5, // hard per-call cap });
const outcome = await client.invoke("browser.session", { duration_seconds: 600 }, { idempotencyKey: savedPurchaseKey, }); console.log(outcome.result, outcome.payment?.transaction);
CLI
npx ausca catalog
npx ausca price document.ocr AUSCA_PRIVATE_KEY=0x... AUSCA_MAX_PAYMENT_USD=0.50 \ npx ausca invoke browser.session '{"duration_seconds":600}' --idempotency-key saved-browser-purchase-0001
Python
pip install ausca
from ausca import AuscaClient
client = AuscaClient.with_local_key(private_key=key, max_payment_usd=0.50) outcome = client.invoke( "browser.session", {"duration_seconds": 600}, idempotency_key=saved_purchase_key, )
A remote MCP server also runs at https://ausca.com/mcp (Streamable HTTP) for discovery, preparation, and state reads; payment always signs on your side, which is why the local server exists.
Every service is an x402 v2 payable resource. An unsigned request returns the exact payment requirement; the client pays it only if it fits your cap, then retries the same bytes with the same idempotency key. Save a unique key before paying and retain it on uncertainty; starting another call with a new key is a new purchase. CLI and paid MCP calls require an explicit key. Resource admission contains private capabilities: never publish the raw result. See recovery examples. Settlement is USDC on Base and every completed invocation carries a receipt with a public, hash-only verification page. Payment rails are pluggable behind one interface; the official @x402/* libraries do all signing.
Document and media services take an immutable artifact commitment instead of raw bytes: npx ausca commit file.pdf uploads through the keyless ingress and returns the commitment the offer input carries.
Every package uses ausca.com as its product home and resolves commercial offer bindings from the live catalog. A registry listing is not a separate service or source of pricing truth.

Release workflows use repository-bound trusted publishing rather than personal registry logins or stored publisher tokens. Each registry binding names auscahq/ausca, its workflow filename and the matching GitHub environment:
| Registry | Workflow | Environment | Tag |
|---|---|---|---|
| npm | npm.yml | npm | npm/ /v |
| PyPI | pypi.yml | pypi | python/ /v |
| crates.io | crates.yml | crates-io | rust/v |
| RubyGems | rubygems.yml | rubygems | ruby/v |
| NuGet | nuget.yml | nuget | dotnet/v |
| pub.dev | pub-dev.yml | pub.dev | dart/v |
A workflow file alone does not establish registry trust. Configure and verify the matching publisher before its first release. New npm bindings must become valid within two days; a pending or expired binding is not ready. Routine releases must not need a browser approval. Push release tags individually: GitHub suppresses tag events when more than three tags are pushed together. The Ruby, NuGet, Rust and Python workflows can also resume from an existing immutable tag by explicit dispatch; never move a published release tag.
